As a loving Shih Tzu owner, it’s natural to want to share every moment, and sometimes even every snack, with your furry companion. The temptation to offer a piece of your healthy fruit can be strong, especially when those big, soulful eyes are looking up at you. However, what’s good for humans isn’t always safe for our canine friends, and this is particularly true for small breeds like the Shih Tzu, who can have sensitive digestive systems and unique dietary considerations. Understanding what fruits can Shih Tzus not eat is not just about avoiding discomfort; it’s about safeguarding their health and well-being.
Shih Tzus, with their adorable squishy faces and playful personalities, are prone to certain health issues that can be exacerbated by inappropriate foods. Their small size means that even a tiny amount of a toxic substance can have a significant impact, and choking hazards are a much greater concern. Their digestive tracts can be more delicate, making them susceptible to upset stomachs, vomiting, and diarrhea from foods that larger, more robust breeds might tolerate. This comprehensive guide will walk you through the fruits that are strictly off-limits, those that require extreme caution, and a brief overview of safe options, always keeping your Shih Tzu’s specific needs in mind.
Understanding Your Shih Tzu’s Unique Digestive Needs
Shih Tzus are a toy breed, and their small stature brings with it a set of dietary considerations that differ from larger dogs. Their tiny mouths and throats make them prone to choking, so any food given as a treat must be cut into very small, manageable pieces. Furthermore, their digestive systems can be quite sensitive. Rich, fatty, or sugary foods, even those considered harmless for humans, can easily lead to gastrointestinal upset, pancreatitis, or weight gain in a Shih Tzu.
Unlike humans, dogs don’t inherently require fruits in their diet. Their nutritional needs are primarily met by a high-quality, balanced dog food. However, in moderation, certain dog-safe fruits can provide beneficial vitamins, minerals, and antioxidants, serving as healthy, low-calorie treats. The key is knowing which ones are truly safe and how to prepare them properly. For a Shih Tzu, even “safe” fruits must be introduced slowly, in very small quantities, and always without seeds, pits, or rinds, which can pose choking hazards or contain toxic compounds.
The Absolute No-Go: Toxic Fruits for Shih Tzus
When it comes to feeding your Shih Tzu, some fruits are unequivocally dangerous and should never be given under any circumstances. These fruits contain compounds that can cause severe illness, organ damage, or even be fatal to dogs, especially small breeds whose bodies are less equipped to process toxins.
Grapes and Raisins: A Severe Threat to Shih Tzus
Grapes and raisins are arguably the most notorious toxic fruit for dogs, and Shih Tzus are no exception. The exact toxic substance is still unknown, but even small amounts can cause acute kidney failure, which can be life-threatening. All forms of grapes are dangerous, including fresh, dried (raisins), and grape products like juice or baked goods.
Symptoms of grape or raisin toxicity in Shih Tzus can include:
- Vomiting
- Diarrhea
- Lethargy and weakness
- Dehydration
- Loss of appetite
- Abdominal pain
- Increased thirst and urination (early sign of kidney damage)
- Decreased urination or absence of urination (sign of severe kidney failure)
Immediate Action: If you suspect your Shih Tzu has ingested even a single grape or raisin, contact your veterinarian or an emergency animal hospital immediately. Time is critical, and prompt veterinary intervention, such as induced vomiting and activated charcoal, can make a significant difference. Never wait for symptoms to appear.
Prevention: Keep all grapes and raisins out of your Shih Tzu’s reach. Be mindful of food items containing them, such as fruit salads, trail mix, or baked goods. Ensure children understand not to share these items with your dog.
Avocados: A High-Fat Risk with Persin
While avocados are hailed as a superfood for humans, they pose multiple risks to Shih Tzus. The primary concern is persin, a fungicidal toxin found in the pit, skin, leaves, and bark of the avocado tree. While the flesh contains smaller amounts, it can still be enough to cause gastrointestinal upset in sensitive dogs like Shih Tzus.
Beyond persin, avocado flesh is remarkably high in fat. For a small breed, consuming high-fat foods can lead to severe digestive issues, including:
- Gastrointestinal Upset: Vomiting, diarrhea, and stomach pain are common.
- Pancreatitis: This is a serious inflammation of the pancreas, which can be life-threatening in dogs. Small breeds, including Shih Tzus, are particularly susceptible to pancreatitis when consuming fatty foods. Symptoms include severe abdominal pain, vomiting, diarrhea, loss of appetite, and lethargy.
Prevention: Never offer your Shih Tzu any part of an avocado. If you have an avocado plant, ensure your dog cannot access it. Be aware that some dog treats include avocado oil for skin and coat benefits, which is generally safe, but whole avocado fruit should be avoided.
Cherries: Cyanide in Pits and Stems
Cherries are another fruit that should be kept far away from your Shih Tzu. The pits, leaves, and stems of cherry plants contain cyanide, a highly toxic substance. If ingested, cyanide interferes with cellular oxygen transport, meaning your dog’s blood cells cannot get enough oxygen, which can quickly become a medical emergency.
Risks for Shih Tzus:
- Cyanide Poisoning: Even a small amount of cyanide from a cherry pit can be dangerous for a tiny Shih Tzu.
- Choking Hazard: The pits themselves are a significant choking hazard for small dogs, potentially leading to airway obstruction.
- Intestinal Blockage: If a pit is swallowed, it can cause a dangerous intestinal blockage.
Symptoms of cyanide poisoning can include:
- Dilated pupils
- Difficulty breathing
- Red gums (bright red mucous membranes)
- Shock
- In severe cases, death.
Prevention: Always remove cherry pits, stems, and leaves before considering offering any fruit, although it’s best to avoid cherries altogether for Shih Tzus given the risks. Securely dispose of pits in a dog-proof trash can.
Tomatoes (Green Parts): Solanine Concern
While ripe, red tomato flesh is generally considered non-toxic to dogs in very small amounts, the green parts of the tomato plant – including the leaves, stems, and unripe (green) tomatoes – contain a toxic alkaloid called solanine. Although a Shih Tzu would likely need to consume a large quantity of the green plant material to become severely ill, it’s safer to err on the side of caution and avoid tomatoes entirely.
Risks for Shih Tzus:
- Solanine Poisoning: Symptoms can include severe gastrointestinal upset (vomiting, diarrhea), lethargy, weakness, dilated pupils, and in rare severe cases, heart issues.
- Pesticides/Herbicides: Tomatoes from a garden may also have residues of pesticides or herbicides, adding another layer of risk.
Prevention: If you have a tomato plant in your garden, ensure your Shih Tzu cannot access it. It’s best to skip offering tomatoes to your Shih Tzu to eliminate any risk.
Citrus Peels and Seeds: Digestive Irritants for Shih Tzus
While the flesh of some citrus fruits, like oranges, is considered safe for dogs in moderation, the peels, seeds, and even the white pith should be avoided for Shih Tzus.
- Peels: Citrus peels contain essential oils and psoralens, which can cause significant gastrointestinal upset, including vomiting and diarrhea, in sensitive breeds. The fibrous nature of the peel is also difficult for small dogs to digest and can pose a choking risk or lead to intestinal issues.
- Seeds: Like many fruit seeds, citrus seeds contain small amounts of cyanide and are a choking hazard.
Prevention: If you decide to offer a tiny, seedless segment of orange flesh, ensure all peel and pith are meticulously removed. Given their sensitive stomachs, it might be best to avoid citrus fruits for Shih Tzus entirely or offer only the smallest, most carefully prepared piece.
Fruits to Offer with Extreme Caution and Preparation for Shih Tzus
Some fruits, while not inherently toxic like grapes, can still pose significant risks to your Shih Tzu due to their pits, seeds, or rinds, or even their sugar content. Careful preparation is paramount.
Apples (Seeds and Core): Choking and Cyanide Risk
Apples are a good source of vitamins A and C, and fiber. However, the seeds contain a small amount of cyanide, and the core can be a choking hazard or cause digestive upset.
For Shih Tzus:
- Always remove all seeds and the core.
- Cut the apple flesh into very small, bite-sized pieces to prevent choking.
- Offer in strict moderation due to natural sugars.
Pears (Seeds and Core): Choking and Cyanide Risk
Similar to apples, pears are rich in copper, vitamins C and K, and fiber. But their seeds also contain traces of cyanide, and the core can be a choking hazard.
For Shih Tzus:
- Thoroughly remove the pit (core) and all seeds.
- Slice the pear flesh into tiny, manageable chunks.
- Avoid canned pears with sugary syrups.
Peaches (Pits): Choking and Cyanide Risk
Fresh peaches offer fiber and vitamin A. However, the pit contains cyanide and is a serious choking hazard for a small Shih Tzu.
For Shih Tzus:
- Completely remove the pit and ensure no fragments remain in the flesh.
- Cut the peach flesh into very small pieces.
- Never offer canned peaches, which are loaded with sugar.
Mangoes (Pits): Choking and Cyanide Risk
Mangoes are a tropical treat packed with vitamins A, B6, C, and E, as well as potassium. But the large, hard pit contains small amounts of cyanide and is a definite choking hazard.
For Shih Tzus:
- Peel the mango completely and remove the pit.
- Cut the flesh into tiny cubes.
- Offer only in moderation due to high sugar content.
Watermelon (Rind and Seeds): Blockage Risk
Watermelon is a hydrating fruit rich in vitamins A, B6, and C, and potassium. The rind and seeds, however, can cause serious problems.
For Shih Tzus:
- The rind is difficult to digest and can lead to gastrointestinal upset or intestinal blockage.
- Seeds, especially in large quantities, can cause intestinal blockage, a medical emergency for small dogs.
- Always remove all seeds and the entire rind.
- Cut the red flesh into very small, seedless pieces.
Safe Fruits for Shih Tzus (In Strict Moderation)
While the focus of this article is on what fruits Shih Tzus cannot eat, it’s helpful to know which fruits can be offered as an occasional, healthy treat, provided they are prepared correctly and given in very small amounts. For more detailed information on beneficial foods, you might want to read what can I give my Shih Tzu to eat.
Remember that “moderation” for a Shih Tzu means truly tiny portions – often just a few pea-sized pieces.
- Apples (without seeds or core): Small, cored, seedless pieces are fine.
- Bananas: High in potassium, vitamins, and fiber, but also high in sugar. Give only tiny slices as a rare treat.
- Blueberries: A superfood packed with antioxidants. Small amounts are safe and easy for Shih Tzus to eat.
- Cantaloupe: Low in calories but high in sugar. Small, deseeded pieces in moderation.
- Cranberries (plain): Unsweetened fresh or frozen cranberries in small quantities. Many dogs don’t like the tartness.
- Cucumbers: Technically a fruit (botanically), excellent for overweight Shih Tzus as they are very low in calories and hydrating. Cut into small, thin slices.
- Mango (without pit or skin): Peeled, pitted, and cut into tiny cubes. High in sugar, so very occasional.
- Oranges (peeled and seedless): Small, peeled, seedless segments. Some Shih Tzus may dislike the strong citrus smell.
- Pears (without seeds or core): Small, cored, seedless pieces.
- Pineapple (peeled and cored): Peeled, cored, and cut into tiny chunks. Avoid canned, sweetened pineapple.
- Pumpkin (pure puree): 100% pure canned pumpkin (not pie filling) is excellent for digestive health. A spoonful can help with both diarrhea and constipation.
- Raspberries: Contains antioxidants and anti-inflammatory properties. However, they contain small amounts of natural xylitol, so limit to very small portions (e.g., 2-3 berries).
- Strawberries: Full of fiber and vitamin C. Cut into small pieces. High in natural sugar, so moderation is key.
- Watermelon (without rind or seeds): Excellent for hydration, especially in hot weather. Ensure all seeds and rind are removed, and cut into small, manageable pieces.

What About Vegetables for Shih Tzus?
While this article focuses on fruits, it’s worth noting that many vegetables are safe and beneficial for Shih Tzus as treats, often posing fewer sugar-related risks than fruits. For a broader understanding of what to avoid in your dog’s diet, consult resources like what not to give a dog to eat. Some safe vegetable options include carrots, green beans, peas, and broccoli (in very small, cooked amounts). However, just like with fruits, certain vegetables like onions and mushrooms are highly toxic and should be strictly avoided. Always consult your veterinarian before introducing new foods, and ensure any vegetable is washed, cut into appropriate sizes, and free of seasonings.
Recognizing Signs of Fruit Toxicity in Your Shih Tzu
Being vigilant is key to protecting your Shih Tzu. Even with the best precautions, accidental ingestion can happen. Knowing the signs of toxicity is crucial for prompt action.
Common signs of fruit toxicity or severe gastrointestinal upset in Shih Tzus include:
- Vomiting: Persistent or severe vomiting.
- Diarrhea: Loose stools, often accompanied by straining.
- Lethargy: Unusual tiredness or lack of energy.
- Loss of Appetite: Refusal to eat or drink.
- Abdominal Pain: Whining, hunching, or reluctance to be touched on the abdomen.
- Tremors or Seizures: In severe cases of toxicity.
- Changes in Urination: Increased or decreased frequency, or difficulty urinating.
- Weakness or Collapse: Extreme cases of toxicity or dehydration.
When to Call the Vet: If you observe any of these symptoms after your Shih Tzu has eaten a questionable fruit, or if you suspect ingestion of a known toxic fruit like grapes, contact your veterinarian immediately. Do not wait for symptoms to worsen. Early intervention can be life-saving. Provide your vet with as much information as possible: what fruit was eaten, how much, and when.
Essential Tips for Feeding Fruits to Your Shih Tzu
To ensure your Shih Tzu’s safety and health when it comes to fruits, follow these essential guidelines:
- Always Consult Your Vet First: Before introducing any new fruit into your Shih Tzu’s diet, especially if they have existing health conditions or a sensitive stomach, have a conversation with your veterinarian. They can provide personalized advice based on your dog’s specific needs.
- Strictly Avoid Toxic Fruits: Grapes, raisins, avocados, cherries, and green parts of tomatoes are absolute no-gos. Be extremely cautious with citrus peels and seeds.
- Proper Preparation is Non-Negotiable:
- Wash thoroughly: Always wash fruits to remove pesticides or dirt.
- Remove all pits, seeds, stems, and rinds: These parts are often toxic or pose severe choking and blockage hazards for small breeds.
- Cut into tiny, bite-sized pieces: This is paramount for Shih Tzus to prevent choking. A piece too large for their small mouths and throats can be fatal.
- Introduce New Fruits Slowly: Start with a tiny, single piece of a new safe fruit and observe your Shih Tzu for any adverse reactions (like digestive upset) for 24-48 hours before offering more.
- Moderation is Key: Fruits are treats, not meal replacements. Even safe fruits contain natural sugars, which can contribute to weight gain or digestive issues if overfed. For a Shih Tzu, a “moderate” portion is truly tiny.
- Monitor for Reactions: Even “safe” fruits can cause an allergic reaction or digestive upset in some individual dogs. Always watch for signs of discomfort or illness.
- Keep it Plain: Never offer fruits that have been sweetened, canned in syrup, or mixed with other ingredients like chocolate, xylitol, or nuts, which can be toxic.
